FIRE surveyed 400 colleges in the United States and found that 62 percent “have policies on their books that restrict a substantial amount of speech,” FIRE’s Greg Lukianoff wrote over at Ricochet. “Speech codes are university policies that prohibit expression protected by the First Amendment. At public colleges, speech codes are unconstitutional,” he also explained.

Lukianoff notes that the trend is in favor of free speech. “Back in 2007, for example, 75% of school surveyed had “red light” codes,” he says.
